In case you're lazy, here's a hint straight from the article: "Arm here also employs some of the biggest branch target and direction prediction buffers that are publicly known in the industry"... Those branch prediction buffers wouldn't be very useful if they weren't used to speculate taken / not taken branches, and their respective targets.

And guess what: "Spectre is a vulnerability that affects modern microprocessors that perform branch prediction" (from Wikipedia).
